** VCF v4.4 is supported but has not been tested with TKGI v1.14.0. To use VCF v4.4, you must use a VCF v4.4-compatible vROps MP for containers, which has not been released.
*** To use Policy API features, you must use NSX-T v3.1.3 or later.
The supported upgrade paths to TKGI v1.14.0 are from Tanzu Kubernetes Grid Integrated Edition v1.13.2, v1.13.1, and v1.13.0.
TKGI v1.14.0 has the following breaking changes:
Warning: The upgrade to TKGI v1.14.0 will switch a “locked” cluster to using the containerd runtime if, between locking the container runtime and upgrading, you ran tkgi update-cluster without including the lock_container_runtime: true parameter in your configuration. For more information on locking the container runtime, see Customize Cluster Container Runtimes Before Upgrading in Upgrade Preparation Checklist for TKGI.
Kubernetes has been upgraded to Kubernetes v1.23.4:
For more information about Kubernetes v1.23, see Kubernetes 1.23: The Next Frontier in the Kubernetes documentation.
Support for the manually installed vSphere CSI Driver has been entirely removed.
Warning: Before upgrading to TKGI v1.14, you must prepare your clusters for removing the manually installed vSphere CSI Driver. For information on how to migrate to automatic vSphere CSI Driver installation, see Switch From the Manually Installed vSphere CSI Driver to the Automatic CSI Driver in Deploying and Managing Cloud Native Storage (CNS) on vSphere.
The kube-apiserver audit.log file is in a new location:
/var/vcap/sys/log/kube-apiserver/audit.log/var/vcap/sys/log/kube-apiserver/audit/log/audit.logTKGI v1.14.0 has the following features and enhancements:
Passes additional CIS Kubernetes Benchmarks:
--protect-kernel-defaults argument is set to true.Supports managing host log customization:
Supports managing cluster log filtering:
LogSink and ClusterLogSink logging. For more information, see Create a Fluent Bit ClusterLogSink or LogSink Filter in Creating and Managing Sink Resources.Supports using the vSphere CSI Driver Topology feature. For more information, see Configure Topology in Deploying and Managing Cloud Native Storage (CNS) on vSphere.
Windows Workers Support Containerd-Runtime Containers
Supports Windows workers with containerd-runtime containers.
Migrates Container Runtimes for Linux and Windows Clusters from Docker to Containerd
Supports migrating existing Linux and Windows clusters from a Docker container runtime to the containerd-runtime:
Note: Linux and Windows clusters that are not locked to the Docker-runtime will automatically migrate to the containerd container runtime during the TKGI v1.14 cluster upgrade. All Docker-runtime clusters must be migrated to containerd prior to upgrading to TKGI v1.15.
For more information, see Prepare Clusters for Automatic Container Runtime Migration in Upgrade Preparation Checklist for Tanzu Kubernetes Grid Integrated Edition.
Supports the following Network Profiles enhancements:
Supports Configuring Additional NCP Parameters
Network Profiles configuration now supports configuring almost all NCP parameters configurable within BOSH. For more information, see extensions in Creating and Managing Network Profiles.
Supports Updating Additional Network Profile Parameters
Network Profiles configuration now supports updating almost all Network Profile cni_configurations parameters on an existing cluster. For more information, see cni_configurations Parameters in Creating and Managing Network Profiles.
TKGI v1.14.0 includes the following additional features:
Supports configuring the TKGI API Operation Timeout length. For more information, see Networking in Installing TKGI on vSphere with NSX-T.
Supports modifying the floating IP pool of an existing cluster. For more information, see fip_pool_ids in Creating and Managing Network Profiles.
Reuses a TKGI API user’s existing service account and ClusterRoleBinding when executing tkgi get-credentials.

Component bumps fix the following Known Issues:
The following TKGI features have been deprecated or removed from TKGI v1.14:
Manual vSphere CSI Driver Installation Support: Support for manually installing the vSphere CSI Driver has been entirely removed in TKGI v1.14. For information on automatic vSphere CSI Driver installation, see Deploying and Managing Cloud Native Storage (CNS) on vSphere.
Flannel Support: Support for the Flannel Container Networking Interface (CNI) is deprecated. VMware recommends that you upgrade your Flannel CNI-configured clusters to the Antrea CNI. For more information about Flannel CNI deprecation, see About Upgrading from the Flannel CNI to the Antrea CNI in About Tanzu Kubernetes Grid Integrated Edition Upgrades.
Docker Support: kubelet support for Docker images has been deprecated and Docker support will be entirely removed in Kubernetes v1.24. TKGI v1.12 and later support containerd images.
VCP Volume Support: VCP volume support has been deprecated. VCP volume support will be entirely removed in TKGI v1.15. For information on how to manually migrate VCP volumes on existing TKGI clusters from VCP to the automatically installed vSphere CSI Driver, see Migrate from VCP to the vSphere CSI Driver in Deploying and Managing Cloud Native Storage (CNS) on vSphere.
Pod Security Policy Support: Kubernetes Pod Security Policy (PSP) support has been deprecated and PSP support will be entirely removed in Kubernetes v1.25. Kubernetes v1.23 and v1.24 provide beta support for Pod Security Admission. For more information, see Pod Security Admission and Enforce Pod Security Standards with Namespace Labels in the Kubernetes documentation.
TKGI v1.14.0 has the following known issues.
Symptom
After you restore Ops Manager and the TKGI API VM from backup, TKGI functions normally, but your TKGI MC tabs include the following error: “…product ‘pivotal-container service’ is not deployed…”.
Explanation
TKGI MC is associated with an Ops Manager with a specific name. If you rename Ops Manager with a new name while restoring, your TKGI MC will not recognize the restored Ops Manager and cannot manage it.
Symptom
The pods in your TKGI Kubernetes clusters on NSX-T become stuck in a creating state. The connections between nsx-node-agent and hyperbus repeatedly close, log Couldn't connect to 'tcp://...' (error: 111-Connection refused), and have a status of COMMUNICATION_ERROR.
Explanation
For information and workaround steps for this Known Issue, see Issue 2795268: Connection between nsx-node-agent and hyperbus flips and Kubernetes pod is stuck at creating state in NSX Container Plugin 3.1.2 Release Notes in the VMware documentation.
Symptom
After clicking Apply Changes on the TKGI tile in an Azure environment, you experience an error ‘…could not execute “apply-changes”…’ with either of the following descriptions:
For example:
INFO | 2020-09-21 03:46:49 +0000 | Vessel::Workflows::Installer#run | Install product (apply changes)

Explanation
The Azure CPI endpoint used by Ops Manager has been changed and your installed version of Ops Manager is not compatible with the new endpoint.
Workaround
Run the following Ops Manager CLI command:
om --skip-ssl-validation --username USERNAME --password PASSWORD --target https://OPSMAN-API curl --silent --path /api/v0/staged/director/verifiers/install_time/IaasConfigurationVerifier -x PUT -d '{ "enabled": false }'
Where:
USERNAME is the account to use to run Ops Manager API commands.PASSWORD is the password for the account.OPSMAN-API is the IP address for the Ops Manager APIFor more information, see Error ‘undefined method location’ is received when running Apply Change on Azure in the VMware Tanzu Knowledge Base.
VMware vRealize Operations (vROPs) does not support Windows worker-based Kubernetes clusters and cannot be used to manage TKGI-provisioned Windows workers.
To monitor Windows-based worker node clusters with a Wavefront collector and proxy, you must first install Wavefront on the clusters manually, using Helm. For instructions, see the Wavefront section of the Monitoring Windows Worker Clusters and Nodes topic.
TKGI-provisioned Windows worker-based Kubernetes clusters inherit a Kubernetes limitation that prevents outbound ICMP communication from workers. As a result, pinging Windows workers does not work.
For information about this limitation, see Limitations > Networking in the Windows in Kubernetes documentation.
You can use Velero to back up stateless TKGI-provisioned Windows workers only. You cannot use Velero to back up stateful Windows applications. For more information, see Velero on Windows in Basic Install in the Velero documentation.
TKGI on Google Cloud Platform (GCP) does not support Tanzu Mission Control (TMC) integration, which is configured in the Tanzu Kubernetes Grid Integrated Edition tile > the Tanzu Mission Control pane.
If you intend to run TKGI on GCP, skip this pane when configuring the Tanzu Kubernetes Grid Integrated Edition tile.
TMC Data Protection feature supports privileged TKGI containers only. For more information, see Plans in the Installing TKGI topic for your IaaS.
Windows worker-based Kubernetes clusters integrated with group Managed Service Account (gMSA) cannot be managed using compute profiles.
On vSphere with NSX-T networking you can use compute profiles with both Linux and Windows worker‑based Kubernetes clusters. On vSphere with Flannel networking, you can apply compute profiles only to Linux clusters.
TKGI CLI does not prevent accidentally reducing a cluster’s control plane node count using a compute profile.
Warning: Reducing a cluster’s control plane node count can destroy the cluster. Do not scale out or scale in existing control plane nodes by reconfiguring the TKGI tile or by using a compute profile. Reducing a cluster’s number of control plane nodes may remove a control plane node and cause the cluster to become inactive.
Symptom
After you delete a VM using the management console of your infrastructure provider, you notice a Windows worker node that had been on that VM is now in a notReady state.
Solution
To identify the leftover node:
kubectl get no -o wide
notReady state and have the same IP address as another node in the list.To manually delete a notReady node:
kubectl delete node NODE-NAME
Where NODE-NAME is the name of the node in the notReady state.
Symptom
You experience a “502 Bad Gateway” error from the NSX load balancer after you log in to OIDC.
Explanation
A large response header has exceeded your NSX-T load balancer maximum response header size. The default maximum response header size is 10,240 characters and should be resized to 50,000.
Workaround
If you experience this issue, manually reconfigure your NSX-T request_header_size and response_header_size to 50,000 characters. For information about configuring NSX-T default header sizes, see OIDC Response Header Overflow in the Knowledge Base.
You must configure a global proxy in the Tanzu Kubernetes Grid Integrated Edition tile > Networking pane before you create any Windows workers that use the proxy.
You cannot change the proxy configuration for Windows workers in an existing cluster.
For vSphere with NSX-T, the HTTP Proxy password field does not support the following special characters: & or ;.
Symptom
You receive the following error after modifying your existing Harbor installation’s storage configuration:
Error response from daemon: manifest for ... not found: manifest unknown: manifest unknown
Explanation
Harbor does not support modifying an existing Harbor installation’s storage configuration.
Workaround
To modify your Harbor storage configuration, re-install Harbor. Before starting Harbor, configure the new Harbor installation with the desired configuration.
Symptom
Permissions are removed from your cluster’s files and processes after resizing the persistent disk during a cluster upgrade. The ingress controller statefulset fails to start.
Explanation
When resizing a persistent disk, Bosh migrates the data from the old disk to the new disk but does not copy the files’ extended attributes.
Workaround
To resolve the problem, complete the steps in [Ingress controller statefulset fails to start after resize of worker nodes with permission denied] (https://community.pivotal.io/s/article/5000e00001nCJxT1603094435795?language=en_US) in the VMware Tanzu Knowledge Base.
Symptom
You experience issues when configuring a load balancer for a multi-control plane node Kubernetes cluster or creating a service of type LoadBalancer. Additionally, in the Azure portal, the VM > Networking page does not display any inbound and outbound traffic rules for your cluster VMs.
Explanation
As part of configuring the Tanzu Kubernetes Grid Integrated Edition tile for Azure, you enter Default Security Group in the Kubernetes Cloud Provider pane. When you create a Kubernetes cluster, Tanzu Kubernetes Grid Integrated Edition automatically assigns this security group to each VM in the cluster. However, on Azure the automatic assignment may not occur.
As a result, your inbound and outbound traffic rules defined in the security group are not applied to the cluster VMs.
Workaround
If you experience this issue, manually assign the default security group to each VM NIC in your cluster.
Symptom
One of your plan IDs is one character longer than your other plan IDs.
Explanation
In TKGI, each plan has a unique plan ID. A plan ID is normally a UUID consisting of 32 alphanumeric characters and 4 hyphens. However, the Plan 4 ID consists of 33 alphanumeric characters and 4 hyphens.
Solution
You can safely configure and use Plan 4. The length of the Plan 4 ID does not affect the functionality of Plan 4 clusters.
If you require all plan IDs to have identical length, do not activate or use Plan 4.
Symptom
After you stop one instance in a multiple-instance database cluster, the cluster stops, or communication between the remaining databases times out, and the entire cluster becomes unreachable.
The following might be in your UAA log:
WSREP has not yet prepared node for application use
Explanation
The database cluster is unable to recover automatically because a member is no longer available to reconcile quorum.
Symptom
Backing up vSphere persistent volumes using Velero fails and your Velero backup log includes the following error:
rpc error: code = Unknown desc = Failed during IsObjectBlocked check: Could not translate selfLink to CRD name
Explanation
This is a known issue when backing up clusters on Kubernetes v1.20 and later using the Velero Plugin for vSphere v1.1.0 or earlier.
Workaround
To resolve the problem, complete the steps in Velero backups of vSphere persistent volumes fail on Kubernetes clusters version 1.20 or higher (83314) in the VMware Tanzu Knowledge Base.
Symptom
The first time that you try to create two Windows clusters at the same time, the creation of one of the clusters fails. If you run pks cluster CLUSTER-NAME to examine the last action taken on the cluster, you see the following:
Last Action: Create Last Action State: failed Last Action Description: Instance provisioning failed: There was a problem completing your request. … operation: create, error-message: Failed to acquire lock … locking task id is 111, description: ‘create deployment’
Explanation
This is a known issue that occurs the first time that you create two Windows clusters concurrently.
Workaround
Recreate the failed cluster. This issue only occurs the first time that you create two Windows clusters concurrently.
Symptom
After running tkgi delete-cluster and cluster deletion has completed, the deleted cluster continues to be listed when running tkgi clusters.
Workaround
You must manually remove the deleted cluster using a customized version of the ncp_cleanup script. For more information, see Deleting a Tanzu Kubernetes Grid Integrated Edition cluster with “tkgi delete-cluster” stuck “in progress” status in the VMware Tanzu Knowledge Base.
Symptom
After you uninstall TKGI, then reinstall TKGI in the same environment, BOSH Director logs errors similar to the following:
.../gems/bosh-director-0.0.0/lib/bosh/director/deployment_plan/cloud_manifest_parser.rb:120:in `parse_vm_extensions': Duplicate vm extension name 'disk_enable_uuid' (Bosh::Director::DeploymentDuplicateVmExtensionName)
Explanation
The pivotal-container-service cloud-config was not removed when you uninstalled the TKGI tile, and it remained active. When you reinstalled the TKGI tile, an additional pivotal-container-service cloud-config was created, causing the metrics_server to fall into a crash-loop state.
Workaround
You must manually remove the pivotal-container-service cloud-config after removing your TKGI deployment, including after removing the TKGI tile from Ops Manager.
For more information, see “Duplicate vm extension name” error when metrics_server runs on Director VM in Tanzu Kubernetes Grid Integrated Edition in the VMware Tanzu Community Knowledge Base.
Symptom
Your TKGI logs include the following error:
'uaa'. Errors are:- Error filling in template 'uaa.yml.erb' (line 59: Client redirect-uri is invalid: uaa.clients.pks_cli.redirect-uri Client redirect-uri is invalid: uaa.clients.pks_cluster_client.redirect-uri)
Explanation
The TKGI API fully-qualified domain name (FQDN) for your cluster contains leading or trailing whitespace.
Workaround
Do not include whitespace in the TKGI tile API Hostname (FQDN) field.
The TMC Cluster Data Protection Backup fails in TKGI environments upgraded from an earlier version.
Symptom
The TMC Cluster Data Protection Backup fails to back up your existing clusters and logs the following error:
error executing custom action (groupResource=customresourcedefinitions.apiextensions.k8s.io, namespace=, name=ncpconfigs.nsx.vmware.com): rpc error: code = Unknown desc = error fetching v1beta1 version of ncpconfigs.nsx.vmware.com: the server could not find the requested resource
Explanation
Kubernetes v1.22 disallows the spec.preserveUnknownFields: true configuration in your existing clusters and the creation of a v1 CustomResourceDefinitions configuration fails.
The TMC Cluster Data Protection Restore operation can fail when restoring multiple Antea resources.
Symptom
The TMC Cluster Data Protection Restore fails and logs errors that requests to restore the admission webhook have been denied.
Explanation
Velero has encountered a race condition while operating a resource. For more information, see Allow customizing restore order for Kubernetes controllers and their managed resources in the Velero GitHub repository.
TKGI does not support environments where there are multiple matching networks, such as a mixed CVDS/NVDS environment.
Symptom
TKGI logs errors similar to the following in an environment with multiple matching networks:
LastOperationstatus='failed', description='Instance provisioning failed:
There was a problem completing your request. Please contact your operations team providing the following information:
service: p.pks, service-instance-guid: ..., broker-request-id: ..., task-id: ..., operation: create,
error-message: Unknown CPI error 'Unknown' with message 'undefined method `mob' for <VimSdk::Vim::OpaqueNetwork:' in create_vm' CPI method
Explanation
TKGI cannot identify which of the matching networks you intend to use and has selected the wrong network.
Occasionally, tkgi update-cluster hangs while updating a Windows worker node instance and the BOSH task cannot finish and exits.
Symptom
The ovsdb-server service has stopped but other processes report that it is running.
Explanation
The ovsdb-server.pid file uses the pid for a process that is not the ovsdb-server.
To confirm that this is the root cause for tkgi update-cluster to hang:
ovsdb-server service has actually stopped, run the PowerShell Get-services command on the Windows worker node.To verify that other processes report the ovsdb-server service is still running:
Review the ovsdb-server job-service-wrapper.err.log log file.
The job-service-wrapper.err.log log file is located at:
C:\var\vcap\sys\log\openvswitch-windows\ovsdb-server\job-service-wrapper.err.log
Confirm that after the flushing processes, the log includes an error similar to the following:
Pid-Guard : ovsdb-server is already runing, please stop it first
At C:\var\vcap\jobs\openvswitch-windows\bin\ovsdb-server_ctl.ps1:30 char:5
+ Pid-Guard $PIDFILE "ovsdb-server"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: ( [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Pid-Guard
To verify the root cause:
Run the following PowerShell commands on the Windows worker node:
$RUN_DIR = "C:\var\vcap\sys\run\openvswitch-windows"
$PIDFILE = "$RUN_DIR\ovsdb-server.pid"
$pid1 = Get-Content $PidFile -First 1
echo $pid1
$rst = Get-Process -Id $pid1 -ErrorAction SilentlyContinue
echo $rst
ProcessName is not ovsdb-server.Workaround
To resolve this issue for a single Windows worker:
Run the following:
rm C:\var\vcap\sys\run\openvswitch-windows\ovsdb-server.pid
ovsdb-server process to start.If LDAP is enabled, Harbor private projects are inaccessible after upgrading to TKGI v1.13.0. For more information, see Private projects become inaccessible after upgrading Harbor for TKGI to v2.4.x with LDAP feature enabled in the VMware Tanzu Knowledge Base.
Microsoft changed Microsoft Windows’ support for tar file commands in the January 2022 Microsoft Windows security patch.
Packaging scripts that use tar commands for Windows worker-based Kubernetes Cluster deployments can fail after the Microsoft tar command patch update has been applied.
The BOSH agent used by vSphere stemcells built by stembuild v2019.43 and earlier use tar commands that are no longer supported and will fail if the Microsoft Windows security patch has been applied.
Workaround
Stembuild v2019.44 and later include a version of the BOSH agent that does not use unsupported tar commands.
If you use vSphere stemcells, use Stembuild 2019.44 or later to avoid the BOSH agent tar error.
Symptom
The pre-start script for tkgi create-cluster fails and logs floating IP pool allocation errors in the pre-start.stderr.log similar to the following:
level=error msg="operation failed with [POST /pools/ip-pools/{pool-id}][409] allocateOrReleaseFromIpPoolConflict &{RelatedAPIError:{Details: ErrorCode:5141 ErrorData:<nil> ErrorMessage:Requested IP Address ... is already allocated. ModuleName:id-allocation service} RelatedErrors:[]}\n"
level=warning msg="failed to allocate FIP from (pool: ...: [POST /pools/ip-pools/{pool-id}][409] allocateOrReleaseFromIpPoolConflict &{RelatedAPIError:{Details: ErrorCode:5141 ErrorData:<nil> ErrorMessage:Requested IP Address ... is already allocated. ModuleName:id-allocation service} RelatedErrors:[]}\n"
Error: an error occurred during FIP allocation
Explanation
TKGI administrators can allocate floating IP pool IP Addresses in a Network Profile configuration. The TKGI control plane allocates IP Addresses from the floating IP pool without accounting for the IPs allocated using Network Profiles.
Workaround
TKGI allocates IP addresses starting from the beginning of a floating IP pool range. When configuring a Network Profile, allocate IP Addresses starting at the end of the floating IP pool range instead of those at the beginning.
kube-apiserver logs are regularly compressed and stored for future reference.
Stale kube-apiserver logs should be deleted when the compressed logs occupy their maximum allocated disk space. The compressed kube-apiserver logs are instead being re-compressed, renamed, and moved to a different location.
In an environment configured with a proxy, automatic vSphere CSI Driver Integration ignores the configured proxy and fails.
Symptom
In environments configured with a Proxy and automatic vSphere CSI Driver Integration enabled, the csi-controller and csi-syncer services log errors similar to the following and fail:
"caller":"vsphere/virtualcenter.go:154","msg":"failed to create new client with err: Post \"...\": dial tcp: lookup ...: no such host"
Workaround
To configure the vSphere CSI Driver to use your proxy:
SSH to TKGI Control Plane VM.
Open the /var/vcap/jobs/csi-controller/bin/csi_controller_ctl configuration file for editing.
Locate the start_csi_controller function in the configuration file:
start_csi_controller()
{
...
export ...
export ...
export ...
...
}
Locate the export commands in the start_csi_controller function and add the following to the group of export commands:
export HTTP_PROXY=HTTP-PROXY
export HTTPS_PROXY=HTTPS-PROXY
export NO_PROXY=NO-PROXY
Where:
HTTP-PROXY is the HTTP Proxy that the vSphere CSI Driver must use.HTTPS-PROXY is the HTTPS Proxy that the vSphere CSI Driver must use.NO-PROXY is a list of host names that the vSphere CSI Driver should not use a proxy for.Restart the csi_controller:
sudo monit restart csi_controller
The Fluent Bit Docker, CRI, Go, Java, and Python multi-line parser does not merge containerd runtime cluster log entries belonging to the same context into a single log entry.
Containerd runtime cluster log entries belonging to the same context are not merged into a single log entry by the Fluent Bit Docker, CRI, Go, Java, and Python multi-line parser.
Symptom
The pre-start script for tkgi create-cluster fails and logs floating IP pool allocation errors in the pre-start.stderr.log similar to the following:
level=error msg="operation failed with [POST /pools/ip-pools/{pool-id}][409] allocateOrReleaseFromIpPoolConflict &{RelatedAPIError:{Details: ErrorCode:5141 ErrorData:<nil> ErrorMessage:Requested IP Address ... is already allocated. ModuleName:id-allocation service} RelatedErrors:[]}\n"
level=warning msg="failed to allocate FIP from (pool: ...: [POST /pools/ip-pools/{pool-id}][409] allocateOrReleaseFromIpPoolConflict &{RelatedAPIError:{Details: ErrorCode:5141 ErrorData:<nil> ErrorMessage:Requested IP Address ... is already allocated. ModuleName:id-allocation service} RelatedErrors:[]}\n"
Error: an error occurred during FIP allocation
Explanation
TKGI administrators can allocate floating IP pool IP Addresses in a Network Profile configuration. The TKGI control plane allocates IP Addresses from the floating IP pool without accounting for the IPs allocated using Network Profiles.
Workaround
TKGI allocates IP addresses starting from the beginning of a floating IP pool range. When configuring a Network Profile, allocate IP Addresses starting at the end of the floating IP pool range instead of those at the beginning.

For more information, see Generate Configuration File and Deploy Tanzu Kubernetes Grid Integrated Edition in Deploy TKGI by Using the Configuration Wizard.Fixes TKGI MC Does Not Support Single-Edge Node Configurations in Automated NAT Mode.
The following TKGI features have been deprecated or removed from TKGI Management Console v1.14:
The Tanzu Kubernetes Grid Integrated Edition Management Console v1.14.0 has the following known issues:
Symptom
The Tanzu Kubernetes Grid Integrated Edition Management Console integration to vRealize Log Insight does not support connections to the HTTPS port on the vRealize Log Insight server.
Workaround
/lib/systemd/system/pks-loginsight.service in a text editor.-e LOG_SERVER_ENABLE_SSL_VERIFY=false.Set -e LOG_SERVER_USE_SSL=true.
The resulting file should look like the following example:
ExecStart=/bin/docker run --privileged --restart=always --network=pks
-v /var/log/journal:/var/log/journal
--name=pks-loginsight
-e TYPE=gear2-vm
-e LOG_SERVER_HOST=${LOGINSIGHT_HOST}
-e LOG_SERVER_PORT=${LOGINSIGHT_PORT}
-e LOG_SERVER_ENABLE_SSL_VERIFY=false
-e LOG_SERVER_USE_SSL=true
-e LOG_SERVER_AGENT_ID=${LOGINSIGHT_ID}
pksoctopus/vrli-journald:v07092019
Save the file and run systemctl daemon-reload.
systemctl restart pks-loginsight.service.Tanzu Kubernetes Grid Integrated Edition Management Console can now send logs to the HTTPS port on the vRealize Log Insight server.
Symptom
If you enable vSphere HA on a cluster, if the TKGI Management Console appliance VM is running on a host in that cluster, and if the host reboots, vSphere HA recreates a new TKGI Management Console appliance VM on another host in the cluster. Due to an issue with vSphere HA, the ovfenv data for the newly created appliance VM is corrupted and the new appliance VM does not boot up with the correct network configuration.
Workaround
Reconfigure virtual machine task has run on the appliance VM.Symptom
Some file arguments in Kubernetes profiles are base64 encoded. When the management console displays the Kubernetes profile, some file arguments are not decoded.
Workaround
Run echo "$content" | base64 --decode
Symptom
